Initial reaction nako for sure is
However, provided the following scenarios are true, then my feelings may vary:
1. If my mom and dad are still on. (Wala nag-buwag)
Reaction: Ahw,

maawayan jud nako akong mama og wala sa oras. Yet, I am going to hide it first sa akong dad, so I'd know the main reason why nabuhat na niya. ( Probably she found out my dad is doing the same thing, that's a possibility. )
2. If my mom and dad are off (Buwag na sila without any chance/with some chance nga magbalik)
Reaction: I'd let my mom. It is her personal life, and I know that she's aware of what she's doing. I'll support her kung asa siya happy. That's my mom, and all I want for her is the best.
